A major fortification south of the Blessed River in the Overriver district of the Pale City, Tares' Keep was constructed in the reign of Tares I, just before the start of the Solemn Age. It was intended to secure the mouth of the river, along with the Old Toll Tower, as well as (nominally) guard the seaward flank of the City from occasional amphibious raids. Since those times, the threat of attack has diminished, and the toll on ships that pass through the mouth of the river has been abolished. The keep, having outlived its usefulness, now exists largely as a training camp for soldiers in Imperial service, and additionally as an extra palace for House Luseysi (or more frequently, honored guests).
